Abstract
A decision feedback equalization ('DFE') technique is suitable for use in a serializer-deserializer ('SERDES') receiver in an integrated circuit (IC). The IC has a summing node coupled to a return-to-zero (“RTZ”) data latch register. The RTZ data latch register has a first (“even”) series of RTZ data latches and a second (“odd”) series of RTZ data latches. A first even tap is coupled to the first even RTZ data latch and provides a feedback signal to the summing node on a first portion of a local clock cycle. A first odd tap is coupled to the first odd RTZ data latch and provides an odd feedback signal to the summing node on a second portion of the local clock cycle.
